Stationary sealing gasket

Abstract

The stationary gasket used in all kinds of dishwashers and similar household appliances, characterized in that; it ensures the sealing not by being compressed but by stretching and ensures sealing in both ways with a single part.

Claims

1. A stationary gasket used in household appliances, characterized in that the stationary gasket ensures a leak-proof sealing in a contact region between a first part and a second part, wherein the sealing is by stretching of the stationary gasket between the first part and the second part, wherein: the first part comprises a first connecting tab, a second connecting tab, an internal surface and an external surface, wherein, the first connecting tab extends laterally from the external surface of the first part; and the second connecting tab extends vertically towards the second part from the internal surface of the first part; the stationary gasket comprises a leg portion comprising a first end and a second end, a hook portion, and a flap portion, wherein, the first end of the leg portion is free and the hook portion laterally extends from the second end of the leg portion in a first direction; and the flap portion laterally extends from the leg portion in a second direction, which is opposite the first direction; the hook portion receives the first connecting tab comprising a top surface and a bottom surface, wherein the hook portion presses against the top surface and interfaces with the bottom surface, wherein the pressing of hook portion against the top surface resists movement of the fluid and the interfacing of the hook portion with the bottom surface prevents vertical movement of the stationary gasket towards the second part; at least a part of the leg portion towards the first end presses against the second connecting tab, wherein the pressing of the leg portion against the second connecting tab resists movement of the fluid; the flap portion interfaces and presses against the second part, thereby resisting movement of the fluid; and the stationary gasket is produced in a single piece by injecting (2K injection technology) a softer thermoplastic material on a rigid plastic before the rigid plastic is moved out of a mold.

(4) The subject matter of the present invention is a gasket which is used in all kinds of dishwasher and similar household appliances, manufactured in single piece by the 2 technology concerning the sealing problems, being grouped easily and not dropping, providing full sealing in both ways with a single part, performing the sealing not by being compressed between two rigid plastics but by stretching and thus, designed for preventing the problems resulting from the faults of operator and characterized by having tub (2) and stationary gasket (1) and tank (3).

(5) In FIG. 1, Boom illustration of the stationary gasket (1) is seen. The stationary gasket (1) provides sealing by being mounted by stretching between lower tank (3) and upper tub (2) since it is produced from soft thermoplastic material.

(6) In FIG. 2, section view of the stationary gasket (1) is seen. The stationary gasket (1) is secured by engaging the housings located on the tank (3) by means of its connecting tabs located thereon. Thus, it cannot be removed from its place during mounting and when the operator mounts the tank (3) with the tub (2), the stationary gasket (1) stretches by contacting the wall of the tub (2) and thus, the gasket is not deformed because of operator's fault and it properly performs the sealing.

(7) The sealing is now discussed in greater detail. In an embodiment, the stationary gasket (1) may be configured to ensure leak-proof sealing in a contact region between a first part and a second part, wherein the first part is the tank (3) and the second part is the tub (2). The first part (3) comprises of a first connecting tab (4), a second connecting tab (5), an internal surface (6) and an external surface (7). The first connecting tab (4) further comprises of a top surface (8) and a bottom surface (9), wherein the first connecting tab (4) extends laterally from the external surface (7) of the first part (3), and the second connecting tab (5) extends vertically towards the second part (2) from the internal surface (6) of the first part (3). The stationary gasket (1) comprises of a leg portion (10) comprising a first end (11) and a second end (12), a hook portion (13), and a flap portion (14). The first end (11) of the leg portion (10) is free and the hook portion (13) laterally extends from the second end (12) of the leg portion (10) in a first direction. The flap portion (14) laterally extends from the leg portion (10) in a second direction, which is opposite the first direction.

(8) In an embodiment, the hook portion (13) receives the first connecting tab (4) comprising the top surface (8) and the bottom surface (9). The hook portion (13) presses against the top surface (8) and interfaces with the bottom surface (9), wherein the pressing of hook portion (13) against the top surface (8) resists movement of the fluid and the interfacing of the hook portion (13) with the bottom surface (9) prevents vertical movement of the stationary gasket (1) towards the second part (2). At least a part of the leg portion (10) towards the first end (11) presses against the second connecting tab (5), wherein the pressing of the leg portion (10) against the second connecting tab (5) resists movement of the fluid and the flap portion (14) interfaces and presses against the second part (2), thereby resisting movement of the fluid.
